BR-202024017291-U2 - Improvement introduced in agricultural machinery for tobacco cultivation.

Abstract

Used in tobacco farming, preferably during harvesting; it stands out for also being able to operate in the application of granular fertilizers. It comprises a main structure (E1) that receives an upper structure (E2) on top of it; a cart (K) is mounted on the main structure (E1) by means of a front support (S1) and a rear support (S2); the cart (K) consists of a horizontal chassis (C), on which a seat (7) is mounted; a receiving box (8); and a platform (9), on which the fertilization module (A) is mounted - in a removable manner - which comprises an upper reservoir (R), which is mounted on an upper base (B1), which in turn is mounted by means of feet (P) on a lower base (B2), which is supported and locked on that platform (9) of the cart (K). Under the upper base (B1) are mounted the drive components of the fertilizer module (A), such as the motor (M) and a programming and control panel (10); and whereby, downstream of the motor (M), a duct (D) is mounted, through which the motor (M) expels the granulated fertilizer contained inside the reservoir (R).

1. 1) IMPROVEMENT INTRODUCED IN AGRICULTURAL MACHINE FOR TOBACCO CULTIVATION, comprising a main structure (E1) consisting of a plurality of profiles; said main structure (E1) receiving on it a horizontal upper structure (E2) also consisting of profiles; said main structure (E1) being mounted on wheels (1), which are driven by means of a motor (2), employing cardan shafts (3) and transmission boxes (4); characterized by the fact that, in the anterior region of the main structure (E1), a transverse beam (5) is fixed, at whose ends are mounted two anterior supports (S1) in the shape of an inverted “L”, at whose lower end is mounted a carriage (K), consisting of a horizontalized chassis (C), at whose rear end is mounted a rear support (S2) in the shape of an inverted “L”, at whose upper end is mounted a clamp (Z), which in turn is mounted on the column (L) of the rear wheel (1); and, in front of the upper support (S2), a seat (7) is mounted on the chassis (C); in front of which is mounted a receiving box (8); in front of which is formed a platform (9); whereby, on the said platform (9) is mounted – in a removable manner – the fertilization module (A), which comprises an upper reservoir (R), which is mounted on an upper base (B1) in the form of a horizontal plate, which in turn is mounted by means of feet (P) on a lower base (B2), which is supported and locked on that platform (9) of the cart (K); wherein, under the upper base (B1) are mounted the drive components of the fertilization module (A), such as the drive motor (M) and a programming and control panel (10); wherein, downstream of the motor (M) is mounted a duct (D), through which the motor (M) expels the granulated fertilizer contained inside the reservoir (R).

Description

Field of invention [001] More specifically, the present utility model refers to an agricultural machine, which is employed in tobacco farming, and preferably for use in harvesting tobacco leaves. The present agricultural machine stands out from the state of the art by having features that allow it – in addition to its primary function of assisting during the tobacco leaf harvesting operation – to also operate for the automatic application of granular fertilizers to the soil, among other inputs that may also be sprayed. State of the art [002] It is known that until recently tobacco farming still employed rudimentary resources in whole or in some stage of its cultivation, mainly in its harvesting, which could only be done manually, employing rudimentary labor from the farmers themselves. In turn, in this method, due to the height of the tobacco plants and the narrow space between the rows of plants, the harvested leaves were deposited in baskets or large boxes, usually made of wood, and pulled by means of animal traction, with one animal and a respective box being used for each space between two rows of tobacco plants, which did not contribute to the productivity of the harvest, and also demanded the raising and maintenance of animals that were adapted to this activity. [003] In order to solve the aforementioned inconveniences, the agricultural machinery industry has for some time developed some alternatives of self-propelled agricultural machines, in the basic form of a tractor, which were designed to move over and along the rows of tobacco plants, as is the case with the object of patent BR 202019008908-9, which proposed a self-propelled agricultural machine, which is equipped, in its structure, with supports that hold the assembly of seats for the workers; and also platforms to support baskets to accumulate the harvested leaves, so that, in this way, the said agricultural machine moves slowly along and between the rows of tobacco plants, allowing the workers, in a seated position, to harvest the leaves manually and deposit them in the baskets, considerably facilitating and speeding up the work. [004] However, tobacco cultivation presents other specific intervention needs, which remain unmet by means of a technology better adapted to its conditions; such as the operation for applying granular fertilizers and other similarly sprayed inputs. To carry out this task, there is knowledge of some types of automatic fertilizer applicators, whose fertilization modules are mounted on an implement in the form of a structure made of metal profiles, which is specifically intended for the application of fertilizer. In some cases, the machine also allows for the function of planting seeds; however, its acquisition cost is relatively high, adding to the inconvenience of needing a traction vehicle, usually an agricultural tractor, which also has a considerable cost for acquisition and maintenance, among other drawbacks. Objectives of the Invention [005] With the aim of solving these inconveniences and limitations, the present utility model was developed. A new constructive configuration is proposed for the aforementioned machine, where the "carts" - which are part of the original AGRICULTURAL MACHINE FOR TOBACCO CULTIVATION - that accommodate the worker and the collection box for the harvested leaves, are adapted to receive, in a removable manner, a module containing a fertilizer applicator mechanism, which operates automatically, releasing fertilizer or other sprayed input along the tobacco cultivation rows. In this way, the present improvement expands the number of uses of the aforementioned AGRICULTURAL MACHINE FOR TOBACCO CULTIVATION, dispensing with the acquisition and use of other implements and a corresponding agricultural tractor, providing greater economy and practicality for tobacco cultivation, among other advantages.
